802.11 non-standard equipment
802.11 non-standard equipment is equipment that seeks to extend the Wi-Fi standard 802.11, by implementing proprietary features.
Chipmaker Atheros sells a proprietary channel bonding feature called Super G〔(Atheros Super G, Atheros Super AG, Super G, Super AG, Atheros Wireless LAN, 2.4 GHz, 5 GHz, 802.11a/b/g, 802.11g, Wireless LAN )〕 for manufacturers of access points and client cards. This feature can boost network speeds up to 108 Mbit/s by using channel bonding. Also range is increased to 4x the range of 802.11g and 20x the range of 802.11b. This feature may interfere with other networks and may not support all b and g client cards. In addition, packet bursting techniques are also available in some chipsets and products which will also considerably increase speeds. This feature may not be compatible with other equipment. Broadcom, another chipmaker, developed a competing proprietary frame-bursting feature called "125 High Speed Mode"〔(Broadcom's 125 High Speed Mode consortium )〕 or Linksys "SpeedBooster", in response to criticism of Super G's interference potential.
U.S. Robotics also had a "MAXg" line of wireless products boasting 125 Mbit/s (actual throughput 35 Mbit/s) and about a 75% increase in signal range from the 802.11g standard.〔(USRobotics presents MAXg wireless: MAXg )〕 Based on tests performed by KeyLabs on March 23, 2005 the MAXg series consistently outperformed the equivalent proprietary solutions and some of the "Draft 802.11n" solutions from other developers; more than one year before commercially available "pre N" or "Draft N" adapters.〔(KL Final Report Template )〕
